ENUM ROMCODE_WRITE(9)

💅 enum romcode_write(9) — like, the Kernel API Manual page, bestie 🎀

okay so this is enum romcode_write(9) from the Kernel API Manual and honestly? it's a little two-constant enum with main character energy ✨ it's the romcode message that gets written by A9 AND read by XP70 — yes bestie, a whole little inter-core love note 🫶

---

🌸 NAME 🌸

enum romcode_write — the romcode message written by A9 AND read by XP70 😭💖 (both of them, no cap, it's a two-way situation)

---

✨ SYNOPSIS ✨

enum romcode_write {
    RDY_2_DS ,
    RDY_2_XP70_RST

};

like, that's the whole thing. two members. iconic, honestly 👑

---

🦋 Constants 🦋

• RDY_2_DS — the value that gets set when the ApDeepSleep state can actually be executed by XP70 😴✨ like, green light, go take that nap
• RDY_2_XP70_RST — the value that gets set once 0x0F has been successfully polled by the romcode 🔥 and then the xp70 goes into self-reset 💀 (yes, it resets itself, dramatic but valid)
